Hi :)
Where in the USA can I buy a 9" beveled disc with 5/8 shaft? (disc only)
 
I really like mine that I got from trugrit.

Very heavy duty and well made, also the edge is beveled which is really nice!

I really want one.

All one piece machined? I've seen a few attached ones, and I think that is opening the door for problems.

Does anyone know if the ones Nathan made Years ago were aluminum or steel? for some reason i thought steel..... is there any benefit to steel?

In my head I can't see if it would vibrate more, or less?

They were hardened steel for durability

It would not vibrate inherently more or less. That is a function of balancing. Mine were balanced to within a few thousands of an ounce inch and did not vibrate. And, since the bore was single point turned in the same setup as the face and OD, zero run out was built in, which eliminated that as a source of vibration. I used two set screws also.

The limiting factor was the common practice of using an electric motor shaft instead of a precision spindle. There's only so much you're going to get out of that, but I think most people found it to be a solid setup.

Thank you for the response :)

any chance you are going to make another run, or possibly if you got any extra laying around? haha (I know that was a good number of years ago)

I made a 56C motor mounting brkt, but spinning that large of a piece of steel isn't in my wheelhouse with what I got.

I'm assuming Yours are flat? or did you have a bevel in yours for longer pieces going across the surface? there seems to be different opinions on that, and I'd love to hear yours.

Thanks.

I did both.

I did a WIP on them here: https://www.bladeforums.com/threads/wip-steel-grinder-disk-machining.1088181/

It was a cool project. I'm proud of the work.
